Only been to one: Starkvegas. It's nicer than you'd think, if you've never been. The cowbells were never an issue. We dominated both games I went to.
I went in 2017. Yes Cowbells are annoying, parking is a chore, and the State fans around me were drunk and stupid. But its a nice little stadium, and I would highly recommend it... especially over Ole Miss.
Ranking best to worst SEC stadium experiences:
Highly recommend
1A Texas A&M: any fan of college football tradition needs to go. the cadets, the crowd interaction, and stadium are great. NICEST FANS IN THE WORLD
1B LSU: Saturday Night in Death Valley and a belly full of Cajun food is hard to beat. Just be prepared for ribbing
3 Tennessee: Now I say this from a person not afraid of high seats, and never experienced a game at Neyland when Tennessee was on a roll. But its one of the prettiest trips, but the stadium is kinda a dump with the puke orange around.
Pretty good:
4 Mizzou: its a nice little stadium, free parking, and good people
5 MSU: see above
Wont go back:
6 Auburn: They were a 6 win team, but still arrogant and vulgar the entire day. The stadium is just an updated version of Legion Field. The scoreboard is sorta distracting.
7. Ole Miss: The most overrated experience Ive ever had. The Grove was a claustrophobic nightmare, and the fans were horrible. I went in 2016 so the experience maybe different amongst them. But the stadium is a rinky dink stadium with nice grass.
